How long can I my Allegro Breeze be plugged in on 30 amps keeping the batteries maintained without damaging them? I fried my batteries on a Class B RV after not being able to check on it for 3 months due to surgery.

Hi Mrpictureman,
Check to see if your coach has a smart charger. A smart charger will have a "float" charging capability. If not, consider purchasing a portable smart charger. You could turn off the coach charger and let the portable smart charger maintain the batteries when the coach is in storage.

Depends a lot on the type of converter/charger you have. Most modern ones will maintain without overcharging. We keep ours plugged in all year, on the road or at home but I do check the batteries at least at 2 month intervals.

Suggest you call Tiffin service at (256) 356-0261 with your VIN number. They will be able to tell what kind of charger you have in your Breeze and best answer the question as it pertains to your particular coach.

I suppose it depends on the type of charger your coach has. My 06 Winne Aspect was plugged in all the time when home for 6 years (20 amp service) and had sat for as long as a year (DW illness) with no noticeable damage to the batts. I left them on also. I leave my now 05 Itasca Meridian plugged in too (especially to run space heaters) and I occasional monitor the battery minder and rarely do I see any current going into the batts. So I assume they are being floated when needed otherwise they are just sitting there at 100%. Some chargers do not float the batts, just on or full charge which can cause excessive gassing. Batts are not designed to just sit and proper charging is a must, so sitting for long periods of time can take a toll but not much choice. Even disconnecting them does not help much as they will self discharge over time. There is a ton of information here and on the web about how to charge and maintain your batts. First thing to find out is what kind of charger do you have and how it operates. I would hope the charger on your rig is much better then on a B class RV.

I keep my coach plugged in 24/7, unless I'm driving it. I am under the impression that most modern RV's charging systems are smart enough not to damage the batteries when plugged into shore power. Make sure you check the water levels in the batteries occasionally, else they will be damaged. I check mine monthly.

Suggest that you call Tiffin service at (256) 356-8661 with your VIN number. They can tell you what kind of charger you have on your Breeze and answer your question. Some Breezes come an inverter/charger, some do not.

The answer depends on your converter, Some converters, say a Progressive Dynamics 9200 series, You can leave it plugged in several YEARS without worrying too much about killing the batteries provided you check and add distilled water as needed (Assumes flooded wet cells, which is what that is designed to charge)

Other units... Like the Magnetek 6300,,,, Depends on how much charge is in the batteries,, Once full, unplug swiftly.

Odds are the older RV had an older, single stage, converter like the Magnetek.

The new one is more likely to have a modern 3-stage like the Progessive Dynamics Intella power WITH charge wizard (like the 9200)
